Game of Thrones was the best for me until season 3 maybe season 4. After that I am completely bored about it. Vikings gets bad in its 4th season which has 20 episodes and right now there is a break until September I think. But it is still better for me. Like Game of Thrones it has blood and gore and guts, lust for peer, plotting, betrayal, but instead of fantasy it is based on historical facts. And the pace of the story is much faster.

Vikings, Black Sails, Turn: Washington's Spies, 24, The Mentalist, The Blacklist, True Detective (Season 1, Season 2 wasn't very good), How to Get Away With Murder... those are the ones I can remember now.
